Description

Technical Field

[0001] This application relates to the field of seedling antifreeze technology, and more specifically, to a seedling antifreeze device for forest cultivation. Background Technology

[0002] In forest cultivation, frost protection is a crucial step in ensuring the healthy growth of seedlings. Especially in cold regions, low temperatures can cause frost damage to the root system and above-ground parts of seedlings, affecting their growth and survival rate. To effectively prevent frost damage, the following are some common measures:

[0003] 1. Select cold-resistant varieties

[0004] When selecting seedlings for forest cultivation, priority should be given to tree species and varieties with strong cold resistance. Different tree species have different tolerances to low temperatures, and selecting tree species adapted to local climate conditions helps reduce the occurrence of frost damage.

[0005] 2. Appropriate planting time

[0006] The timing of planting is crucial to the survival and growth of seedlings. Generally, planting should be avoided during cold seasons (such as winter or late autumn), and instead, it should be done in the relatively warm spring or autumn to prevent seedlings from being damaged by frost in the cold weather after planting.

[0007] 3. Use antifreeze covering materials

[0008] In winter or on cold nights, seedlings can be protected with covering materials (such as straw mats, cotton cloth, non-woven fabric, etc.) to reduce the risk of frost damage.

[0009] These materials help maintain soil temperature and provide extra protection for seedlings, especially during cold snaps.

[0010] 4. Prune appropriately

[0011] Proper pruning removes weak branches and withered parts that are susceptible to frost damage. This not only improves the seedlings' frost resistance but also promotes healthy plant growth.

[0012] 5. Soil insulation and warming

[0013] Applying insulating materials (such as humus or hay) to the base of seedlings can raise the soil temperature and slow down the freezing process. Preventing excessive freezing of the soil ensures that the root system is not damaged at low temperatures.

[0014] These frost protection measures can effectively improve the frost resistance of seedlings during forest cultivation, promoting their healthy growth. If you have more specific questions about forest cultivation or climate conditions, I can provide you with more in-depth advice.

[0015] The prior art publication number CN221784836U provides a seedling antifreeze device for forest cultivation. This device, through the setting of heat-insulating sponge, can perform a second heat insulation work on forest seedlings, forming an additional heat insulation layer, improving the overall heat preservation effect, reducing the risk of cold damage to forest seedlings, and further improving the antifreeze effect of the device.

[0016] Although the existing technical solutions described above can achieve the relevant beneficial effects through the existing technical structure, they still have the following drawbacks: when the device is in use, it achieves frost protection for the seedlings, but it is not convenient to automatically remove the frost protection when the temperature is suitable, which leads to the need for manual operation, resulting in low efficiency and poor practicality.

[0017] In view of this, we propose a frost protection device for seedlings used in forest cultivation. Utility Model Content

[0035] Please refer to Figures 1-3. This application provides a technical solution:

[0036] A seedling antifreeze device for forest cultivation includes a fixed frame 1, a threaded rod 2, a movable frame 3, a transmission mechanism 4, and a heat preservation cover 5. The threaded rod 2 is rotatably connected inside the fixed frame 1.

[0037] The movable frame 3 is slidably fitted within the fixed frame 1;

[0038] The transmission mechanism 4 is rotatably connected to the movable frame 3;

[0039] The heat insulation cover 5 is mounted on the movable frame 3.

[0040] Specifically, the bottom of the fixed frame 1 is connected and fixedly installed with two plug rods 101, the top of the fixed frame 1 is connected and fixedly installed with a motor 102, the output end of the motor 102 is connected and fixedly installed with the threaded rod 2, and a rack 103 is connected and fixedly installed on one side of the fixed frame 1.

[0041] Furthermore, two insert rods 101 are fixedly connected to the bottom of the fixing frame 1, and a motor 102 is fixedly connected to the top of the fixing frame 1. The output end of the motor 102 is fixedly connected to the threaded rod 2, and a rack 103 is fixedly connected to one side of the fixing frame 1.

[0042] Furthermore, the inner wall of the heat insulation cover 5 is filled with heat insulation material, and multiple electric heating wires 501 are installed and fixedly mounted on the inner wall of the heat insulation cover 5. A connecting frame 502 is rotatably connected to the top of the heat insulation cover 5, and a driven wheel 503 is fixedly connected to the top of the heat insulation cover 5. The driven wheel 503 is meshed with the driving wheel 402 for transmission.

[0043] In addition, two positioning rods 301 are slidably mounted on the movable frame 3, and the positioning rods 301 are movably inserted into the connecting frame 502.

[0044] The implementation principle of the seedling antifreeze device for forest cultivation in this embodiment is as follows: When it is necessary to protect the seedlings in the forest from freezing, firstly, the insertion rod 101 on the fixing frame 1 is inserted into one side of the seedling. Then, according to the size of the seedling, a heat preservation cover 5 of appropriate size is installed. One end of the connecting frame 502 on the heat preservation cover 5 is inserted into the moving frame 3 and then fixed by the positioning rod 301. When it is necessary to protect the seedlings from freezing, the motor 102 drives the threaded rod 2 to rotate, so that the threaded rod 2 drives the moving frame 3 to move down. Then, under the action of the rack 103, the transmission wheel 403 drives the driving wheel 402 connected to the rotating shaft 401 to rotate, so that the driving wheel 402 drives the heat preservation cover 5 connected to the driven wheel 503 to rotate, so that the bottom end of the heat preservation cover 5 is inserted into the soil around the seedling. Then, when the temperature is too low, the electric heating wire 501 is used to raise the temperature to achieve the antifreeze of the seedlings.
